Two separate trip circuit supervision functions are included: TCSSCBR1 for power
output X100:PO3 and TCSSCBR2 for power output X100:PO4. TCSSCBR1 function
is blocked by the master trip TRPPTRC1 and TRPPTRC2 and the generator circuit
breaker open signal, whereas TCSSCBR2 function is blocked by the master trip
TRPPTRC6 and the field excitation open signal.
It is assumed that there is no external resistor in the circuit breaker
tripping coil circuit connected in parallel with the circuit breaker's
normally open auxiliary contact.
Set the parameters for TCSSCBR1 properly.
